Saira (سائرة) is an Arabic name meaning "traveller" or "wanderer" — from the root s-y-r, related to movement and journeying.
Saira is widely used across the Arab world, Pakistan, and the South Asian diaspora. Today it appears increasingly in Western records.
Saira does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Saira reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
